thanks for the reply! i wasnt sure of the properties, but thought it was a cool idea if it would've worked. i currently use a piece of travertine in my conventional oven to cook my pizzas and it works great but eventually cracks. i just thought the thickness may have played into it. oh well... as i said work in the tile/granite industry. im sure ill be able to come across some bricks, cinder blocks over the course of the next year and will then just buy the remaining items needed
